# Approvals, Runtime Files, and Gmail Triggers

> Pause tool calls for approval, pass files between tools, and start runs from Gmail or schedules.

## What's New

### Human-in-the-Loop Approvals

Gate any agent tool call behind a human decision. Mark a tool as requiring approval and the run pauses when that tool is about to fire, so a person can approve or reject the action before it happens. This is built for tools with real-world side effects, like sending an email or updating a record. See [Approvals](/docs/production/approvals).

### Runtime Files Between Tools

Tools within a single agent run can now pass files to one another. A tool that produces a file, such as an attachment saved from an incoming email, makes it available to a later tool that consumes it, so multi-step document workflows hold together from start to finish.

### Gmail Inbox Triggers

Start an agent automatically when an email arrives. Connect a Gmail inbox as a trigger and incoming messages kick off a run, turning your agents into always-on inbox responders. See [Triggers and runs](/docs/concepts/triggers-and-runs).

### Scheduled Runs

Tasks now have a Schedule tab for running them on a recurring schedule directly from the dashboard, with no external scheduler required.

## Improvements

* Agent overview now shows a seven-day run summary and indicates which agents are shared with the project
* A new Trigger column on run listings shows what started each run
* Clickable resource links in skill instructions
* Trigger event errors appear in a dedicated column with one-click copy
* API keys now show their expiry date in the dashboard and via the API
* Broader image support, including HEIF, with correct handling of image orientation

> **Note**
>
> Approvals are configured on the agent revision, so every change to an approval policy is versioned. Rolling an agent back restores its previous policy alongside the rest of its wiring.
